VERY disappointing, The truss rods are bent, pushed into the truss rod cavity. Looks like someone tried to dig under the nuts to get a wrench on them I emailed the seller, there is supposed to be a seven day return policy.
In th factory , we used a curved gouge to chisel out material under the rods. This was done to about 99% of all instruments.
The rod curl is extremely common. It is due to the materials the rods are made of and the way the rods opperate.
I use a SNAP-ON 1/4" open end wrench where the head is set at nearly a right angle to the shaft. I back off the nuts .. Then remove the truss rod bar. (thats the aluminum piece)
.
Next I flatten the bar as they usually are chewed up from being tensioned.
